For a movie of showing the effect of cholera exotoxin on human cells, see the Theriot Lab Website at Stanford University Medical School. Click on Vibrio cholerae colonizing human cells. 3. Enterotoxins. A number of bacteria produce exotoxins that bind to the cells of the small intestines. Most of these toxins catalyze the ADP-ribosylation of host cell proteins that turn the synthesis of the metabolic regulator molecules cyclic AMP (cAMP) or cyclic GMP on and off in intestinal mucosal cells.
DEFINITION of 'Encryption'. Encryption is a means of securing data using a password (key). The encryption process is simple â data is secured by translating information using an algorithm and a binary key. When the data needs to be read back, the code is decrypted using either the same key or a different key depending on the type of encryption used.
A cryptographic algorithm (also called a encryption algorithm) is a A cryptographic algorithm is a mathematical function that computes a result from one or several input values. Overview Edit. Cryptographic algorithms specify the operations of encrypting, decrypting, authenticating, digitally signing, and verifying digital signatures or authentication codes. Algorithms are defined in a cryptographic system and a supporting CKM system for data protection, key protection, key generation, key establishment (exchange, agreement, distribution), key update, key destruction, etc. â 1  NIST Special Publication 800-152, at 127.
